**(a) Documentation of Audit Strategy, Audit Plan, and Significant Changes (SA 300):**
The auditor of Z Ltd. is required to document the following:
1. **The Overall Audit Strategy**: The documentation of the overall audit strategy is a record of key decisions considered necessary to properly plan the audit and to communicate significant matters to the engagement team. It details the scope, timing, and direction of the audit.
2. **The Audit Plan**: The documentation of the audit plan is a record of the planned nature, timing, and extent of risk assessment procedures and further audit procedures at the assertion level in response to the assessed risks. It serves as a record of proper planning of the audit procedures that can be reviewed and approved prior to performance.
3. **Significant Changes and Reasons**: The documentation must record any significant changes made to the overall audit strategy or the audit plan during the audit engagement, and the reasons for such changes. This record explains why the changes were made (e.g., due to the discovery of material misstatement in inventory valuation or the unexpected acquisition in Z Ltd.) and details the final strategy and audit plan adopted.
**(b) Definition and Structure of "Those Charged with Governance" (TCWG) (SA 260):**
"Those Charged with Governance" refers to the person(s) or organization(s) (e.g., a corporate trustee) with responsibility for overseeing the strategic direction of the entity and obligations related to the accountability of the entity. This includes overseeing the financial reporting process.
**Key characteristics and structures of TCWG:**
- **Inclusion of Management**: In some entities, TCWG may include management personnel, such as executive members of a governance board or an owner-manager.
- **Diversity of Structures**: Governance structures vary widely depending on the entity's size, ownership, and legal environment. Some entities have a supervisory board separate from the executive board, while others perform both functions via a single board (e.g., company directors).
- **Collective Responsibility**: In most entities, governance is a collective responsibility of a governing body (such as a board of directors, partners, proprietors, trustees, or equivalent).
- **Smaller Entities**: In smaller or family-owned entities, a single person may be charged with governance (such as the owner-manager or a sole trustee).
- **Communication Agreements**: If the governance structure is not formally defined, the auditor must discuss and agree with the engaging party on the appropriate persons with whom to communicate, based on the auditor's understanding of the entity's structure under SA 315.
**(c) Legality of Mutual Fund Investments by Co-operative Societies (Section 32 of Central Act):**
According to Section 32 of the Central Co-operative Societies Act, 1912, a co-operative society may invest or deposit its funds only in:
1. A Government Savings Bank.
2. Any of the securities specified in Section 20 of the Indian Trusts Act, 1882.
3. Shares, securities, bonds, or debentures of any other co-operative society with limited liability.
4. Any co-operative bank, other than a Central or State co-operative bank, as approved by the Registrar on specified terms and conditions.
5. With any bank or person carrying on the business of banking, approved by the Registrar.
6. Any other manner permitted by the rules or by a special or general order of the Central or State Government.
**Conclusion for Helping Hands Co-operative Society:**
In the given case, the society invested its idle funds in **blue chip mutual funds** (equity market investments). This type of investment is **not** covered under the permissible modes of investment listed in Section 32 of the Central Act, unless there is a specific permission or government order allowing it. Since the society made an unauthorized investment of funds, the statutory auditor was correct in issuing a **qualified opinion**. The management went wrong by violating the provisions of Section 32 of the Central Act.
